To all whom it may concern:

Be it known that I, 'FRAN'K PARDINI, a citizen of/the United States, residing at Carson City, in the county of Ormsby and Stateof Nevada, have invented certain new and useful Improvements in Non-Refillable Botwith the same.

' when the contents of the bpttle is beinga secondary neck 5 tles, of which the following is a specification.

This invention relates to non-refillable bottles, and'more particularly to that class of non-refillable bottles in which the neck of the bottle is provided with an enlargement for receiving an expanslble stopper that is inserted in the neck of the bottle after the same is (filled so as to thereafter.

permit the contents to be emptied," but prevent refilling of the same.

. One of the objects of the invention is to provide a novel form of guard for theexpansible stopper which will effectually prevent unscrupulous persons from tampering Another object of the invention is to provide means for holding the expansible stopper at all times in itsseated position except emptied. I

A further object of the inventronus to provide a bottleof this character. which ,is

simple in construction, cheap tomanufacture, ahd-eiiicient and positive in its operation. a

With these and other objects in view, the invention consists in. the novel features of construction and; arrangement of the parts designams the neck of a bottle that is pro vided with an enlargement 2 forming a stopper-receiving chamber i-E. This enlargement -,expands abruptly at the top so as to pro duce a shoulder 4, and from this shoulder.

the enlargement 3 contacts downwardly into that connects with the body 6 of the bottle.

to collapse as shown in A substantially cone-shaped stopper 7 preferably comprises a body of compressible and expansible material, such, for instance, as rubber, and is shaped to approximately conform to the shape of the chamber 3 in the neck of'the'bottle so that having nce been inserted inthe neck of the bottle it cannot be readily withdrawn.

The stopper 7 comprises a-holi ow body portion having relatively thin Wall in-order that the same may be easily inserted within the bottle neck and on the upper Wall there'- of is formed a plurality of spaced lugs 8. Formed on the lugs 8 and. projecting upwardly therefrom is a plurality of flexible members 9 which are normally in engagement with the shoulder 41: to hold the stopper in its seated position. The members 9 are of such size as to have a resistance that Will normally hold the, stopper seated within the enlargement 3 so as to prevent refilling of the bottle when the .same is inverted, but

such resistance is overcome by the weight of; the liquid within the bottle when the same is inverted to empty the contents thereof, the weight of the liquid overcoming the resistance of the members 9 and causing the same s Fig. 2 of the draw ings in dotted lines. 7 i

It isevident' from the foregoing that the members 9 can be constructed of practically any flexible material, however rubber would serve very eficiently. Anysuitablemeans can he provided for attaching the members 9 to the lugs 8 such for instance as having the lower extremities of the members 9 ems bodied therein. 'Itis to be understood however that I am not be limited to this specific construction.

The lugs 8 form a limiting means to prevent the stopper from seating on the shoul? (ler at when the stopper is in-its raised or unseated positlon.

The neck '1 has a shoulder 10 formed therein a suitable distance above the enlargemerit '3, and extending upwardly at an angle to the shoulder is a groove or cut-out portion 11, which terminates a suitable distance from the mouth of the neck. I

An annular groove is formed in the neck a slight distance-above the shoulder 10' d is adapted to extend in a plane at right angles to the cut-out portion 11, and registers with a similar groove in a guard 12 when the guard is inserted Within the neck with its lower face seated on the shoulder 10- gasket is to annular A gasket 13 is provided for reception in the groove of the guard and neck, which form and thickened at a certain point, clearly shown in Fig. 1.. lhe groove mentioned, extends at an angle which is not parallel to the base of the guard, consequently there will be a force exerted at the point where the gasketis lowest, toward the opposite side of the guard; and likewise there will be a force exerted at the point where the gasket is highest, toward the opposite side of the guard, this force tending to force the guard into the position shown in Fig. 1.

The guard comprises a hollow body portion, and on its upper angular face is provided with a plurality of discharge openings 14, which extend at an angle to the opening of the bottle neck in order to prevent unscrupulous persons trom tampering with the stopper by inserting a wire or other instrument through said openings.

From the above dez'cription taken in connection with the accompanying drawing, the advantages of the construction will be readily appreciated by 'those skilled in the art to which the invention appertains, and while 1 have described the principle of operation of the invention, together with the device which I now consider to he the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made as are within the scope of the claims.

I claim 1. A. non-refillable bottle comprising a stopper mounted in an enlarged portion of the neck of said bottle, lugs vtermed on said stopper and carrying flexible members for engagement with a shoulder formed by said iasaeae enlarged portion to hold the stopper non anally in engagement with the enlarged portron, a gasket carried within a groove formed in said guard and adapted to engage a groove in the bottle neck, and a cut-out portion in said bottle neck against which the upper end of the guard is adapted'to abut to prevent removal of the same. f

- and described.

3. A bottle including an enlarged neck portion, a stopper in said enlarged portion, the interior Wall of said enlarged portion tapering outwardly toward the upper portion thereof, a series of lugs carried on the upper face of said stopper, flexible means connecting said lugs and the upper shoulders of said enlarged portion, a guard in the neck of said bottle above said enlarged portion, said guard and said neck being provided with a complemental groove, said groove entending at an angle relative to the base of said guard, a gasket arranged in said groove, a cut-out portion in said neck, for the reception of the upper extremity of said guard, substantially as described.

In testinion whereof I afiix my signature in presence 0 two Witnesses.
